Description

Power rail for electronic shelf labels

[0001] The present invention relates to a power rail for electronic shelf labels.

[0002] The Electronic Shelf Label (ESL) system uses ESL tags to link with point-of-sale (POS) devices to provide product pricing information, as well as display various promotional information such as unit price, sale price, regular price, product display location, point information, and display quantity, thereby assisting with product purchasing and store operations. These ESLs are installed on power rails and can receive power and connect to data communication links, either wired or wireless, from the power rail.

[0003] The power rail according to the prior art has problems such as the electrodes being placed on the front, which is not aesthetically pleasing, and the electrodes being exposed on the exterior, which is unsafe. In addition, the prior art has problems such as the electrodes being placed on the back, which requires through-holes for tag electrode connection, which complicates the manufacturing process and reduces the aesthetics of the final product. In particular, the through-holes are exposed in areas of the power rail where the ESL is not located, which raises concerns about electrode contamination and deterioration of the aesthetics. In addition, the open back structure prevents double-sided tape from being attached to a flat surface, which is unsafe due to device exposure. In addition, the straight electrode structure causes the device size to become excessively large when multiple electrodes are configured.

[0004] The present invention provides a power rail for an electronic shelf label having a compact size and simple appearance and capable of installing a battery-less electronic label and sensor.

[0062] The electrode part constituting the power rail (10) for the electronic shelf label is composed of a main body and a plurality of electrodes spaced apart from each other on the inside of the main body, and the plurality of electrodes can be housed in the main body while the outside can be exposed to the outside. The electrode part can be configured in a form in which at least one electrode is mounted on the inside in a 'ㄷ' shape. Here, the 'ㄷ' shape can vary depending on the viewing direction such as the top, bottom, left, right, etc. For example, the electrode part can be in a 'ㄷ' shape when viewed from the bottom of Fig. 9a. In addition, the electrode part can be configured to be bendable at at least one point. For example, a groove having a predetermined depth can be formed in the inside at at least one point of the electrode part. Here, the at least one point can be a first point or first and second points. When the electrode part has grooves of a predetermined depth at the first and second points, first and second electrodes spaced apart from each other may be installed from one side of the electrode part to the first point, a third electrode may be installed between the first and second points, and fourth and fifth electrodes spaced apart from each other may be installed between the second point and the other side of the electrode part. The electrode part may be bent in a direction where one side and the other side of the electrode part meet with the first and second points as the center. In addition, the first and second electrodes and the fourth and fifth electrodes of the electrode part face each other, and the third electrode may be positioned between them. In detail, referring to FIGS. 8, 9A, 10, and 11, the electrode part (200) may be composed of an electrode receiving bar (210) and a plurality of electrodes (220). The plurality of electrodes (220) may be, but are not limited to, a ground electrode, positive and negative electrodes for power supply, electrodes for data transmission, etc. The electrode unit (200) is electrically connected to the auxiliary device (300). The electrode receiving bar (210) may be configured in the shape of a flat plate of a predetermined length corresponding to the longitudinal direction of the rail body unit (100) and may be configured of a material that can be bent by an external force.The upper surface and side surface of the electrode receiving bar (210) have a shape corresponding to the lower surface (140) of the rail body part (100) of FIG. 8, the inner surface of the first and second extension parts (150, 160), and the upper surface of the first and second horizontal protrusion parts (151, 161), so that when the electrode part (200) is inserted into the second receiving groove (102) of the rail body part (100), the upper surface and side surface of the electrode receiving bar (210) can be configured to be in close contact with the lower surface (140) of the rail body part (100), the inner surface of the first and second extension parts (150, 160), and the upper surface of the first and second horizontal protrusion parts (151, 161).

In this case, as described in the embodiment of Fig. 9a, the first and third electrodes (221, 223) face each other, and the second and fourth electrodes (222, 224) face each other, so that the fifth electrode (225) is positioned above the first to fourth electrodes (221, 222, 223, 224). In addition, the electrode portion (200) forms a fastening receiving groove (201).

[0071] Referring to FIG. 9c, in various embodiments, the electrode receiving bar (210) may be composed of first to third electrode receiving bars (210a, 210b, 210c).
